Reitz and published by . This book was released on 1978 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Robert Schultehenrich dam was inspected. The purpose of the inspection was to make an assessment of the general condition of the dam with respect to safety, based upon available data and visual inspection, in order to determine if the dam poses hazards to human life or property. Failure would threaten the life and property of three families and cause appreciable damage to associated farm buildings and one power transmission line. Our inspection and evaluation indicates the dam is deficient in that the spillways are inadequate. Considering the small volume of water impounded, the large floodplain downstream and the three groups of farm buildings downstream, one-half PMF is the appropriate spillway design flood. The dam will begin to be overtopped by a 10% PMF. The dam will also be overtopped by a 100-year frequency flood. Other deficiencies observed were steep downstream slope, lack of wavewash protection on the upstream face of the dam, lack of erosion protection in the emergency spillway, heavy growth of trees on the slopes of the dam and lack of seepage and stability analyses records.

This book was released on 1978 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is an earth structure built in a narrow draw in the uplands of the Missouri River Bluffs. An 8-inch steel pipe (principal spillway) is provided to drain off excess water from the lake. Additional spillways (emergency spillways), flat channels excavated in earth, are provided at each abutment. Our inspection and evaluation indicates that the spillway does not meet the criteria set forth in the guideilnes for a dam having the above size and hazard potential. The dam will begin to be overtopped by a flood having a discharge (peak and volume) equal to 35% of the PMF. The dam storage and principal spillway will contain a 1% chance flood (100-year flood) without overtopping the emergency spillway. Other deficiencies observed by the inspection team were tree growth starting on the downstream face, and shallow erosion channels on the downstream face and at the toe of the dam on the west slope.

The purpose of the inspection was to make an assessment of the general condition of the dam with respect to safety, based upon available data and visual inspection, in order to determine if the dam poses hazards to human life or property. Our inspection and evaluation indicates that the dam is deficient in that the spillways do not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential and which require that the spillway be capable of passing a one-half PMF (Probable Maximum Flood). The probable maximum flood is defined as the flood discharge that may be expected from the most severe combination of critical meteorological and hydrologic conditions that are reasonably possible in the region. The dam will begin to be overtopped by a flood having a discharge (peak and volume) equal to 20% of the PMF. The spillways will pass a 1% chance flood (100-year flood) without overtopping, which is a flood that has a 1% chance of being exceeded in any given year.

This book was released on 1978 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is an earth structure built in the uplands of Sehrt Creek, 2-1/2 miles from the edge of the Missouri River Valley. There is no principal spillway. There are two emergency spillways. At the east end is an emergency spillway about 180 feet long on a flat grade in virgin soil approximately 50 feet wide and 3 feet deep. At the west end is a smaller capacity spillway which is a dip in a road with low point more than 2 feet higher. Our inspection and evaluation indicates the dam is deficient in that the spillways are inadequate. The guidelines for a dam having the above size and hazard potential require that the spillway be capable of passing a one-half PMF (Probable Maximum Flood). A 25% PMF will begin to overtop the dam. The dam and spillways are adequate to contain the 100-year flood. Our inspection and evaluation indicate significant tree and underbrush growth on both faces of the dam which could lead to conditions causing rupture of the dam. Other deficiencies found are lack of erosion protection on the upstream slope of the dam, no effective erosion protection on the spillways and lack of seepage and stability analyses records.

This book was released on 1978 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is an earth structure built in the upper end of a (draw) in the hilly ground along the Missouri River on the fringes of the loess blown in from the river bottom. A spillway was cut into the earth slope on the northeast end of the dam. At some time, a concrete sill was constructed across the spillway channel about 20 feet downstream from the centerline of the dam apparently to control erosion of the spillway bottom. Our inspection and evaluation indicates that the spillway meets the criteria set forth in the guidelines for a dam having the above size and hazard potential. The principal spillway will pass a one-half Probable Maximum Flood without overtopping the dam. Our inspection and evaluation indicates heavy tree growth on both faces of the dam which could lead to conditions causing rupture of the dam. Other deficiencies were inadequate erosion protection of the upstream slope of the dam and spillway and lack of knowledge of the location and condition of a pipe reported to be under or through the dam.

Sauthoff and published by . This book was released on 1980 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the visual inspection and the results of the hydrologic/hydraulic investigations, the present general condition of the dam is considered to be somewhat less than satisfactory. Deficiencies were noticed during the inspection and are considered to have an adverse effect on the overall safety and future operation of the dam. Evidence of seepage, soft and wet ground near the toe of the center of the dam; soft ground and flowing water at the intersection of the toe of the dam and the right abutment; and running and standing water and cattails downstream of the toe of the dam was observed. The right bank of the outlet channel for the emergency spillway at a point adjacent to the dam was eroded to an extent that spillway releases within the capacity of the outlet would not be confined to the channel. Damage by unconfined spillway releases to the dam and to other areas downstream of the dam can occur during periods when lake outflow passes the emergency spillway. Erosion of the grass covered upstream face of the dam apparently by wave action and/or by fluctuations of the lake surface level has created a near vertical bank approximately 6-to-12 inches high at the normal waterline.

Reitz and published by . This book was released on 1978 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is an earth structure built in the hilly ground at the west edge of the floodplain of Femme Osage Creek. Normal rainfall, runoff, transpiration, evaporation and seepage either through the dam abutments or the rock in the reservoir all combine to maintain a relatively stable water surface elevation. Our inspection and evaluation indicates the dam is deficient in that it has no spillway. The guidelines for a dam having the above size and hazard potential require that the spillway be capable of passing a Probable Maximum Flood (PMF). A PMF will overtop the dam to a maximum depth of 1.9 feet with a maximum flow of about 600 cubic feet per second. The dam is also deficient in that extensive and serious seepage through and under the dam embankment is occurring and there is erosion and possible sloughing on the downstream slope.

This book was released on 1978 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is an earth structure built prior to 1961 in the rolling topography on a tributary of Augusta Tavern Creek. There is an emergency spillway at the west abutment of the dam, an earth channel excavated in virgin soil. Our inspection and evaluation indicates that the dam is deficient in that the spillway is inadequate. Considering the small volume of water impounded, the large floodplain downstream and the three groups of farm buildings downstream, one-half Probable Maximum Flood (PMF) is the appropriate spillway design flood. A 20% PMF will begin to overtop the dam. The lake and spillway are adequate to contain a 100-year flood, which is a flood that has a 1% chance of being equalled or exceeded in any given year. Other deficiencies noted by the inspection team were tree growth on the upstram and downstream slopes of the dam and lack of erosion protection on the upstream slope and in the spillway of the dam.

Zaman and published by . This book was released on 1980 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Johnson County Dam A-1 was inspected by a team of engineers. The purpose of the inspection was to make an assessment of the general condition of the dam with respect to safety, based upon available data and visual inspection, in order to determine if the dam poses hazards to human life or property. Our inspection and evaluation indicates the spillway does not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. The spillway will not pass the probable maximum flood without overtopping but will pass 25 percent of the probable maximum flood and will pass the 100-year flood (one percent probability flood). The spillway design flood recommended by the guidelines is 50 to 100 percent of the probable maximum flood. Considering the small volume of water impounded behind the dam, the valley below the dam and the estimated hazard zone, the spillway design flood should be 50 percent of the probable maximum flood. The probable maximum flood is defined as the flood discharge which may be expected from the most severe combination of critical meteorologic and hydrologic conditions which are reasonably possible in the region.

Book excerpt: Riss Lake Dam was inspected to make an assessment of the general condition of the dam with respect to safety, based upon available data and visual inspection, in order to determine if the dam poses hazards to human life or property. Our inspection and evaluation indicates the spillway does not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. The spillway will not pass the probable maximum flood without overtopping but will pass 90 percent of the probable maximum flood, which is greater than the estimated 100-year flood. The spillway design flood recommended by the guidelines is 100 percent of the probable maximum flood. The probable maximum flood is defined as the flood discharge which may be expected from the most severe combination of critical meteorologic and hydrologic conditions which are reasonably possible in the region. Deficiencies visually observed by the inspection team were erosion of the upstream face due to wave action, ponded water on the dam crest due to poor drainage of rainwater, trees and brush growing on the embankment, animal burrows, and seepage at several locations below the dam.

This book was released on 1980 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the inspection was to make an assessment of the general conditions of the dam with respect to safety, based upon available data visual inspection, in order to determine if the dam poses hazards to human life or property. The inspection and evaluation indicate that the spillways do not meet the minimum criteria set forth in the recommended guidelines for an intermediate dam having a high hazard potential. The Probable Maximum Flood is the appropriate spillway design flood. The spillway will pass the 100-year flood (a flood having a 1 percent probability of being exceeded in any year) without overtopping the dam. The spillways will pass 22 percent of the Probable Maximum Flood without overtopping the dam. The Probable Maximum Flood (PMF) is defined as the flood that may be expected from the most severe combination of critical meteorologic and hydrologic conditions that are reasonably possible in the region.
